How to limit the maximum number of running pods

We currently have around 20 jobs. These jobs create one pod each, but we want to make sure that only one of these pods can run at a time, keeping the rest of them in pending status. Increasing the resource limitations makes them to run one by one but I want to be sure that this is always the behaviour.

Is there any way of limiting this concurrency to 1, let's say per label or something similar?

Use ResourceQuota resource:

apiVersion: v1
kind: ResourceQuota
metadata:
  name: pod-demo
spec:
  hard:
    pods: "5"
